Claims14
A method of manufacturing a biocompatible tissue implant, comprising:
- providing a pre-chilled solution comprising a foam forming, biocompatible polymer in a solvent, said solvent having a freezing point;
- providing a biocompatible polymeric reinforcement member, said reinforcement member soluble in said solvent;
- placing the polymeric reinforcement member in a cavity of a suitable mold;
- pre-chilling the mold;
- adding the solution to the cavity of the mold such that at least a part of the cavity is filled with the solution and at least part of the reinforcing member is in contact with the solution;
- quenching the reinforcement member and the mold to below the freezing point of the solvent prior to lyophylizing;
- and,
- lyophilizing.
